1 Claim. (Cl. 40-140) The present invention relates to an easilymountable and dismountable placard or sign board suitable for severalpurposes, such as general publicity list of prices in magazines,time-tables, useful information, and others.

The dismountable placard, object of the present invention consists of aplurality of parallel bars or sign supporting members provided wihtlongitudinal grooves and separated by spacers or folding members, saidbars being maintained in position by means of a suitable frame. Theletters employed to form the inscription are provided, on one of theirfaces, with suitable pins which can be inserted into two parallelgrooves, whereby the desired sentences or words may be formed.

According to a further feature of the invention, the grooves and spacersare stamped or cast in one integral, metallic piece, or made of plasticmaterial by any one of the known processes. Moreover, if desired, smallplates may be made with only two grooves, which are suitable forexhibition of prices in shopwindows and for other purposes.

Still further features of the present invention are provided, as will beseen hereafter.

The object of the invention is represented, as nonlimiting examples, inthe attached drawings, wherein:

Fig. l is a perspective view of a sign board supporting member and aspacer or holding member;

Fig. 2 is a cross section through a sign board assembly made accordingto the present invention; and

Fig. 3 is a cross section similar to Fig. 2 drawn to enlarged scale andillustrating the manner in which a sign board supporting member isassembled with a sign board.

The invention may be carried out as shown in Fig. 1, wherein a signsupporting member 26 is provided with a central longitudinal projection27 and with two parallel lateral projections 28; said projections areprovided with longitudinal lugs 29 of slightly bulged concave surface,the edges of which are spaced from each other so that grooves 30 areobtained, in which the pins 6 of the letters or numbers can be inserted.In order to space the members 26, elongated holding members 31 areprovided having a longitudinal lower projection 32 and oppositelyarranged holding projections 34.

"ice

In order to mount and dismount the sign supporting members 26 in aconvenient manner, the holding members 31 are fixed to a plate 33, asshown in Fig. 2 in such a way that the holding projections 34 of theholding members 31 overlap slightly the lateral projections 28 of thesign board supporting members 26. By means of this arrangement the signboard supporting members 26 can be easily placed and withdrawn from thesign board as illustrated in Fig. 3. In order to assemble the signsupporting member 26 in the sign board the upper lateral projection ofthe member 26 is slipped under the holding projection 34 of one of theholding members, then the sign supporting member 26 is tilted towardsthe plate 33 and shifted downwardly so that the lower projection 21becomes located underneath the holding projection 34 of the lowerholding member 31. In removing the sign supporting member 26 the same isshifted first in upward direction and then swung outwardly.

The dismountable sign board above described in its various features, isvery useful in movie theaters, railroad and highway stations, as well asin commercial and industrial establishments.

Having thus described the invention, what I claim is:

A demountable sign board comprising in combination, a flat base; aplurality of elongated sign supporting members each having alongitudinal and a pair of parallel lateral projections, saidlongitudinal and lateral projections being respectively provided withlongitudinal lugs having concavely bulged surfaces the edges of whichare spaced from each other so as to form grooves, said elongated signsupporting members being arranged on said flat base parallel to andslightly spaced from each other so as to form elongated spaces betweenadjoining lateral projections; elongated holding members arranged insaid spaces, each having oppositely arranged holding projectionsextending along the length of the holding members and adapted to overlapthe lateral projections of adjacent elongated supporting members and tohold the same, and means securing at least said elongated holdingmembers to said fiat base.
